Answer:
For the first artifact, it looks likes it was used for math. It looks like the language on the tablet is Cuneiform. This artifact represents the Record Keeping characteristic of civilization. Math and writing were used to record data and trades between people and civilizations.
It looks likes the second image is art. I think the purpose of this artifact is to show how ancient people "wrote" things down in a way when they didn't have written developed. This artifact could also have been made to show hierarchy. This could represent the specialized workers.
The third is statues of people. Some civilizations put these in the tombs with their dead family members because they believed it protected them and helped them on their journey in the after life. This represents the religion characteristic.
The last is the building of temples or altars. This became easier to do after the Bronze age. The purpose of this was to honor ancient civilization's gods. For example, the pyramids were built as burial sites for the pharaohs because the Egyptian's believed that the pharaohs were gods in human form. But the characteristics that the last artifact represent are improved technology and religion. Architecture could also be one of them.
